中学英语语法详解大全(讲义) Part 12 被动语态 语态是动词的一种形式,表示主语和谓语动词之间的关系。英语动词有两种语态: 要点提示 1. 只有需要动作对象的及物动词才有被动语态形式; 2. 不及物动词(短语)由于不接宾语,所以没有被动语态形式,但有些不及物动词如果与某些介词或副词构成动词短语,可以有被动语态形式。如: The baby can be looked after by me. 这个婴儿可以由我照料。 1 被动语态的构成 1. 被动语态由“助动词be+及物动词的过去分词(p.p.)”构成,助动词be有时态、人称和数的变化。 1 及物动词 be+及物动词(短语)的过去分词 (时态变化体现在助动词be上) I am often praised by the teachers. 我经常受到老师们的表扬。 The sports meeting will be put off . 运动会将被推迟。 The street is being widened . 那条街道正在加宽。 The fire has been put out . 火已经被扑灭了。 2 情态动词+及物动词 情态动词+be+及物动词(短语)的过去分词 This work must be finished before tomorrow. 此工作必须在明天以前完成。 主动语态变为被动语态: 2. 各种时态被动语态的构成 要点提示 1. 主动语态变为被动语态时,其谓语动词的时态要与原句时态保持一致,其谓语动词的人称和数要与新主语保持一致; 2. 将来进行时以及现在完成进行时、过去完成进行时、将来完成进行时的被动语态很少见。 练一练 把下列句子改写成被动语态: 1.

He was seen to enter the house by me. 我看到他进入房子。 2. 句中含有双宾语,每个宾语都可变为被动语态的主语,即其被动语态有两种形式,但多以间接宾语作主语。若将直接宾语作主语,这时要在间接宾语前加上介词to 或for 。如: I gave Jim a book yesterday. Jim was given a book yesterday(by me). A book was given to Jim yesterday(by me). 昨天我给了吉姆一本书。 3. 句中的动词短语要作为整体看,介词或副词不可拆开或漏掉。如: My grandma looks after my little brother. My little brother is looked after by my grandma. 奶奶照看我的小弟弟。 4. 主动语态中的宾语是从句,变成被动句时可使用it 作为形式主语,变为“It be+ 过去分词+原宾语从句”结构或“Sb./Sth. be+ 过去分词+to do ”结构。如: They say that she is very clever . It is said that she is very clever. 或 She is said to be very clever. 他们说她很聪明。 5. nobody, no one 等否定意义的不定代词作主语,变为被动句时,将其变为anybody, 且将谓语动词变为否定形式。如: Nobody can stop the wheel of history. The wheel of history can’t be stopped by anybody . 没有人能够阻挡历史的车轮。 练一练 1. Paul doesn’t have to be made _. He always works hard. A. learn B. to learn C. learned D. learning 2. Who _this book _?
